What about "faux" commercials for the time being, just to get you guys a break and get the timing worked out before you actually take on a contractual commitment? It would also demo your abilities to host commercials.
You know, something like the commercials Mike Richards does, but with a fake product.
(Or is that kind of cheesy?)
Edit: I mean, in addition to Reg's idea - which I think is brilliant.
Edit 2: Maybe we can track down The President for a sound bite! "Hi, this is The President, and it's not needed to tell me listen to the Calgarypuck Radio. It is something that I have already did."
